Reads all buffered activities. Call this function periodically (between frames, not in a tight loop). Every times this function is called, all buffered activities are consumed (appended to InOutActivities buffer) and a new request is fired to refill the internal buffer. The activities are streamed from the most recent to the oldest.
True if all activities were consumed, false otherwise.
